Watch The Protector. Do not try to follow the plot. It's awful and jumps around. The fight scenes though? Especially the staircase? They're magical.
The Man From Nowhere was pretty good. It's a bit intense at parts, but all around the choreography was amazing. South Korea and China both have a lot of great films out there right now, from romances to heist films to comedies. I'm glad Netflix and Hulu both have picked some of them up. Japan really needs to step up their game.
